Can I use Telerik's JS library?

For example: I want to hide any HTML element by using fade out animation in Telerik Websource Javasctip library. Following code block is giving a Javascript error.

    
            <form id="form1" runat="server"> 
        
                <telerik:RadScriptManager ID="scriptManager" runat="server"> 
        
                </telerik:RadScriptManager> 
        
                <div> 
        
                    <asp:Label ID="lbl" runat="server" Text="Deneme deneme test deneme" BackColor="#CCFFCC" 
        
                        BorderColor="#33CC33" BorderStyle="Solid" BorderWidth="1px" Font-Bold="True" 
        
                        Font-Overline="False" Font-Size="XX-Large"></asp:Label> 
        
                </div> 
        
                <script language="javascript" type="text/javascript"> 
        
                $telerik.addExternalHandler(window,"load",function(){ 
        
                    $TWA.FadeOutAnimation("<%=lbl.ClientID %>",5000,12,0,100,false); 
        
                });     
        
                </script> 
        
                </form>

GridScrolling: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method

IE 6 SP2
Telerik.Web.UI version: 2008.2.723.20
(Runtime Version: v2.0.50727)

This bug is identical to:
http://www.telerik.com/community/forums/thread/b311D-bdakdk.aspx

except that it applies to the RadGrid (Telerik.Web.UI.GridScrolling), not the RadSplitter.

When an iframe containing a grid is closed immediately after the iframe contents are loaded (but before the DOM is ready?), a race condition can occur where a javascript error is thrown:

Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method

The error is thrown from Telerik.Web.UI.GridScrolling.dispose() when:
$removeHandler(window,"resize",this._onResizeDelegate)
is called before the setTimeout in Telerik.Web.UI.GridScrolling._initializeDimensions() can fire.

Thanks & HTH,
Russell

Label not visible when in insert mode

Hi,

I am trying to make a GridBoundColumn in the radgrid not to be visible when in insert mode.

I was able to make the textbox for the column to behave not to be visible. But the label attached to it is still visible.

I did as below to make the textbox not to be visible in the itemdatabound event ,

if

(e.Item is GridEditFormInsertItem && e.Item.IsInEditMode)
{
GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;

TextBox

txtDesc = (TextBox)insertItem["Description"].Controls[0];
txtDesc.Visible = false;

}

How to make the label attached to it also not to be visible?
Please help. Urgent

Regards

Sujith

Problem with filtering

Hi,

I am using filtering functionality. I have set AllowFilteringByColumn="True" Still the filtering is not working.

I have binded the grid in page load event.

If I write the binding code in not ispostback then the grid does not appears after the filtering is done.

If I write the code in postback event of page load grid appears but without filtered data.

Please tell me which property should I set or I am doing binding of grid in some wrong event. Shall I bind grid in event other than page load?

Thanks,
Rahul

PageSize and custom pager templates

I've run into a weird little problem with page sizes and a custom pager template.
I'm using the javascript supplied in the sample http://demos.telerik.com/ASPNET/Prometheus/Grid/Examples/Programming/PagerTemplate/DefaultCS.aspx
to change page number and page size, which works perfectly fine.
The problem is that when I construct the Grid initially (i.e. !IsPostBack) I'm setting grid.PageSize and grid.MasterTableView.PageSize to 30 (our preferred default).
That works fine until I hit a page change link when the page size subsequently resets itself back to the default value 10.
If I change the page size from the client, the new page size is retained on subsequent post-backs, otherwise it remains at 10.
It looks like the viewstate value of the page size is somehow not picking up the server side change despite it being done before the grid is added to the control tree.

Is there any way around this problem, perhaps something else I can set server side which will fix it?
I can provide a simple example if that helps.

CheckChildNodes and OnClientNodeChecked

I am looking at the sample http://demos.telerik.com/ASPNET/Prometheus/TreeView/Examples/Functionality/CheckBoxes/DefaultCS.aspx
and it says that
"This example also demonstrates the use of the OnClientNodeChecked event, which allow fine-tuning of the RadTreeView behavior. This event is used to check/uncheck all child nodes if the parent node is checked/unchecked."

But this sample does not use the OnClientNodeChecked event. Instead it uses the CheckChildNodes property.

But I am actually looking for the Javascript to "uncheck" all of child nodes if it is unchecked (it sounds like the way the example used to work). But not to auto-check all child nodes if checked. Does this example still exist?

Thanks!

Worst components to deploy?

Come on, I'm using the latest ASP.NET AJAX and Ive never experience such of hard time deploying controls. I have try other components and they usually add to your project the images need it .. etc.. why these controllers don't and i have to take extra steps to get them going, how annoying.

I read some where that i good options is to setup a virtual directory so i don't have to worry over and over about all the files need it, and guess what !!!! people don't explain correctly the steps on how to accomplish this so the controllers will find the necessary files.

Telerik developers ??

Controlling sort order in RadTreeView with an Object Data Source

I'm using a treeview bound to an object data source which calls a stored proc with an order by in the select statement. It doesn't look like I'm able to control the display order of items within the same level. Any tips on how to do that?

[Solved] DetailTable CommandItem style being ignored

my RadGrid has this child DetailTable:

    
            <DetailTables>           
        
                <Telerik:GridTableView  
        
                    Width="100%" 
        
                    Name="offenderCharges"  
        
                    DataKeyNames="OffenderChargeID"  
        
                    AutoGenerateColumns="false"  
        
                    EditMode="EditForms"  
        
                    Caption="&nbsp;"  
        
                    CommandItemDisplay="Top"  
        
                    CommandItemStyle-Font-Bold="true"  
        
                    NoDetailRecordsText="No Charges"  
        
                    CssClass="setMargin"> 
        
                    <ParentTableRelation> 
        
                        <Telerik:GridRelationFields MasterKeyField="OffenderID" DetailKeyField="OffenderID"/> 
        
                    </ParentTableRelation> 
        
                    <CommandItemSettings AddNewRecordText="Add new Charge" RefreshText="" RefreshImageUrl="~/1.gif" /> 
        
                    <Columns> 
        
                        <Telerik:GridEditCommandColumn ButtonType="LinkButton" UniqueName="editColumn" ItemStyle-ForeColor="#333333" ItemStyle-Font-Bold="True" /> 
        
                        <Telerik:GridButtonColumn CommandName="Delete" ButtonType="LinkButton" Text="Delete" UniqueName="deleteColumn" ConfirmText="Delete charge?" ConfirmTitle="Delete" ItemStyle-ForeColor="#333333" ItemStyle-Font-Bold="True" /> 
        
                        <Telerik:GridBoundColumn HeaderText="OffenderChargeID" UniqueName="OffenderChargeID" DataField="OffenderChargeID" Visible="False" ReadOnly="true"/> 
        
                        <Telerik:GridBoundColumn HeaderText="OffenderID" UniqueName="OffenderID" DataField="OffenderID" ReadOnly="true" Visible="false"/> 
        
                        <Telerik:GridDropDownColumn HeaderText="Charge" UniqueName="Charge" DataField="ChargeID" DropDownControlType="RadComboBox"/> 
        
                        <Telerik:GridDropDownColumn HeaderText="Victim #" UniqueName="VictimNumber" DataField="VictimNumber" DropDownControlType="RadComboBox"/> 
        
                        <Telerik:GridDropDownColumn HeaderText="Relationship" UniqueName="Relationsip" DataField="OffenderVictimRelationshipTypeID" DropDownControlType="RadComboBox"/> 
        
                    </Columns> 
        
                </Telerik:GridTableView>                 
        
            </DetailTables>

...problem is, the attribute CommandItemStyle-Font-Bold="true" doesnt work. none of the CommandItemStyles seem to work (font bold, italic, background color, etc).

they work in my MasterTableView, but not in the DetailView.

im using the office2007 skin.

any idea whats up?

thanks,
matt
